How to complement the regular expression so that it does not work in the presence of the exact word?

Question

Regular Expressions

There is a redirect
RewriteRule (.*)\/([0-9]+)$ $1 [R=301,L]
How to make the view addresses
/какой то номер на конце
redirect (this is implemented in the line above)
But if the view address at the end
/page/какой то номер
is not redirected?
Thanks

It is necessary to use negative lookahead in the regular expression:
RewriteRule (.*)(?!page/)\/([0-9]+)$ $1 [R=301,L]
